THILLGCOUPLING.

SPECIFICATION forming part of Letters Patent N o. 742,237, dated October27, 1903.

Application tiled January Z, 1903. `Serial No. 137,594. (No model.)

' To all 'whom t may concern:

v secured to the axle.

The construction and operation aswell as the advantages of our inventionwill fully appear hereinafter and by reference to the accompanyin'gdrawings, in which- Figure l is a top plan view of our invention; Fig.2, a front View in elevation; Fig. 3, a side view in elevation, and Fig.4 a detail view of the pivoted jaw'detached from the coupler.

Referring to the drawings, in which similar reference charactersindicate corresponding parts throughout the several views, A

represents one of our improved thill-coup- 1ers, shown attached to theaxle B by means of a clip C, which is secured in holes D in the couplerby means of nuts E. The Yfront of the coupler A consists of a rigid jawF having a pintle G secured thereto,'and a jaw II, pivoted at the otherside of the coupler A and having a hole h to register with the pin,`

tle G. The fixed jaw F is cut down at its front and has formed integraltherewith or' rigidly secured thereto an offset I, which extends acrossthe front of the device and has a slot z' in its free end to receive alug K on the front of the'pivoted jaw I-I. In order to hold the pivotedjaw in a locked position, I

provide a spring-catch L on the front of offset I, having a shoulder Z.at its free end to t into angular grooves M and M in the edge of theoffset I andlug K, respectively, which are in alinement when the pivotedjaw F is in a locked position.

It will be readily understood from this description that thills providedwith irons having horizontally-bored heads are coupled by sliding themon the pintles G when the jaws I-I are open. The jaws H are then closedand held in a locked position by means of springcatches L.

Having thus described our inyeution, what we claim is Y A l. In athill-coupler, a fixed jaw having an olfset across the front of thecoupler, a pivoted jaw, means to secure the thill between said jaws, anda spring-catch secured'to said offset and adapted to engage the pivotedjaw to hold it in a locked position, substantially as shown anddescribed.

2. In a thill-cou-pler, a fixed jaw having an offset across the front ofthe coupler, a horizontal swinging jaw, means to secure the thillbetween said jaws, and a spring-catch secured to said offset and adaptedto engage the pivoted jaw to hold it in a locked position, substantiallyas shown and described.

3. In a thill-coupler, a fixed jaw having an offset across the front ofthe coupler, a pintle secured to said fixed jaw, a pivoted jaw having ahole to register with said pintle, and a spring-catch secured to saidoffset and adapted to engage the pivoted jaw to-hold it in a lockedposition, substantially as shown and described. .f

4. In a thill-coupler, a fixed jaw, a pivoted jaw, an offset on saidfixed jaw, having a'slot and an angular groove, a lug on the pivoted jawto register with said slot and grooved in alinement with the groove insaid odset when in a locked position, and a spring-catch having a headto register with said grooves, substantially as shown and described.

5.,- A thill-coupler secured to a wagon-axle by means of a clip passingthrough holes in the coupler, a xed jaw seenred thereto, ai grooves inthe offset andl lug, substantially horizontally-swinging jaw pivotedthereon, a as shown and described. pintie secured to the fixed jaw toregister In testimony whereof We hereto aiiix our with a hole in theswinging jaw when locked, signatn res in the presence of two Witnesses.5 an offset on the front of the fixed jaw having s A a slot and anangular groove, a lug on the ggERRODAb/XUGH pivoted jaw to register withsaid slot `mid grooved in alinement with the groove in said Vitnesses:offset when in a locked position, and a spring- S.
